Why on Earth would someone need to be anonymous on here?
There are many reasons I can think of. General need to avoid publicity because they have a high public profile and don't want that to get in the way? Imagine if a rockstar or movie star or a President or Prime Minister wanted to participate? Lower levels of the same thing, also apply and are more likely.
Perhaps they are in the industry or related industry in a capacity that would also distract from their personal involvement (i.e. they don't want to have a professional or corporate involvement).
Maybe they have some general issues with being identified - court orders, people they're trying to avoid (for legitimate reasons - family disputes, for example).
That's just the first ones off the top of my head.
If someone's a troll or abusive, report them to the moderators. They're very quick to take action in genuine cases and I think very reasonable in how they take action (gentle warnings, firm warnings, thread locks, bans, etc, all when appropriate and never with an overly harsh approach that I've seen).
So the reasons exist and I don't think we should exclude people just for wanting a little anonymity. Afterall, as I said my site is more a technical exercise - it could easily have just been a mockup - someone could fake a profile with literally minutes of work if that was needed to gain access and they were that keen.
Also, I've seen plenty of "verifiable" folks who really shouldn't be allowed to post anything publically, ever. I'm sure we've all encountered such people!
